Analgesic Effects of Ropivacaine Combined With Dexmedetomidine in Transversus Abdominis Plane Block in Patients Undergoing Laparoscopic Cholecystectomy: A Systematic Review and Meta-Analysis.

Purpose: This review aimed to conduct a meta-analysis of published randomized controlled studies (RCTs) comparing the effectiveness of dexmedetomidine (DEX) combined with ropivacaine versus single ropivacaine in transversus abdominis plane block (TAPB) for postoperative analgesia after laparoscopic cholecystectomy (LC). The purpose was to investigate whether DEX combined with ropivacaine in TAPB for postoperative analgesia in LC is superior to single ropivacaine administration.

Design: A Systematic Review and Meta-analysis.

A Practical Predictive Model Based on Ultrasound Imaging and Clinical Indices for Estimation of Response to Neoadjuvant Chemotherapy in Patients with Breast Cancer.

Purpose: Clinical responses of neoadjuvant chemotherapy (NACT) are associated with prognosis in patients with breast cancer. The selection of suitable variables for the prediction of clinical responses remains controversial. Herein, we developed a predictive model based on ultrasound imaging and clinical indices to identify patients most likely to benefit from NACT.

One-stage reconstruction of complex soft tissue defects in the hands using multidigit, chimeric, lateral arm, perforator flaps.

Purpose: To describe our experience using microsurgically fabricated, multilobed, chimeric, lateral arm (LA) flaps to reconstruct hand injuries with complex, multidigit, soft tissue defects and to evaluate the morbidity and esthetic and functional outcomes of the donor sites.

Methods: We performed a single center, retrospective analysis of 21 patients with hand wounds treated from October 2013 to February 2016. All patients underwent reconstruction using multilobed, chimeric, free, LA flaps.

B7-H3 Overexpression Predicts Poor Survival of Cancer Patients: A Meta-Analysis.

Background: B7-H3 exhibits altered expression in various cancers. However, the correlation between B7-H3 expression and prognosis of cancer patients remains controversial. Therefore, we elicit a meta-analysis to investigate the potential value of B7-H3 in the prognostic prediction in human cancers.

Radiological studies on the best entry point and trajectory of anterior cervical pedicle screw in the lower cervical spine.

Objective: To explore the best entry point and trajectory of anterior cervical transpedicular screws in the lower cervical spine by radiological studies, and provide reference for clinical application.

Methods: Fifty patients were scanned by computed tomography and confirmed no obvious defect of the cervical spine. On horizontal axis, camber angle (α) and axial length (AL) were measured from C3 to C7.

[Posterior reduction and interbody fusion for the treatment of thoracolumbar fractures and dislocations].

Objective: To explore efficacy of posterior reduction and interbody fusion in treating thoracolumbar fractures and dislocations.

Methods: From August 2004 to May 2009, 24 patients (18 males and 6 females with an average of 38.2 years, ranged 24 to 56 years old) were treated.

The study on comparison of 3 techniques for transarticular screw placement in the lower cervical spine.

Study Design: Prospective comparative study.

Objective: To compare 3 techniques for transarticular screw placement in the lower cervical spine.

Summary Of Background Data: The transarticular screw is found to have satisfactory biomechanical stability.

Posterior short-segment fixation and fusion in unstable Hangman's fractures.

Study Design: A retrospective study. OBJECTIVE.: To introduce the method of C2-C3 posterior short-segment fixation and fusion in unstable Hangman's fracture and to evaluate the clinical effects.

[Operative treatment of old acetabular fractures].

Objective: To explore the operative methods and effects of treatment of old acetabular fractures.

Methods: From October 2001 to October 2007, 26 patients with old acetabular fractures were treated with operation including 21 males and 5 females with an average age of 34 years ranging from 18 to 65 years. On the basis of the three-dimensional computed tomography, all cases were diagnosed and classified according to Letourne-Judet classification, 9 cases were posterior wall fracture, 3 cases were lateropulsition fracture, 7 cases were lateropulsition and posterior wall fracture, 2 cases were posterior column and posterior wall fracture, 2 were T-shape fracture, 3 were dual column fracture.

Clinical application of C2 laminar screw technique.

C2 laminar screws have become an increasingly used alternative method to C2 pedicle screw fixation. However, the outcome of this technique has not been thoroughly investigated. A total of 35 cases with upper cervical spinal instability undergoing C2 laminar screw fixation were reviewed.

[Surgical treatment and classification of multiple-level noncontignous thoracolumbar fractures].

Objective: To explore the surgical treatment and classification of multiple-level noncontiguous thoracolumbar fractures.

Methods: From December 2005 to December 2008, 24 patients with multiple-level noncontignous thoracolumbar fractures were treated by surgical operation included 16 males and and 8 females with a mean age of 36 years old ranging from 18 to 63 years. According to the ASIA grade of spinal nerve function there was 1 case in grade A, 2 cases in grade B, 2 cases in grade C, 8 cases in grade D and 11 cases in grade E.

[Analysis of safety and effect of the technique of reconstructing anterior and middle columns by single posterior approach].

Objective: To explore the safety and effect of the technique of reconstructing anterior and middle column by posterior approach in treatment of lumbar burst fractures.

Methods: From July 2005 to January 2007, 22 patients of lumbar burst fractures (18 males and 4 females, the age was from 28- to 57-years-old with an average of 42.7 years) were treated as the following surgical procedures: based on the routinal posterior approach, one of the transverse process of the injured vertebral was incised to get access to the lateral side of the injured vertebral body.

[Selective treatment of thoracolumbar fracture with posterior monosegmental pedicle screw fixation].

Objective: To explore the clinical effects of posterior monosegmental pedicle screw fixation in selective treatment of thoracolumbar vertebral fractures.

Methods: From June 2005 to June 2008, 28 patients (male 17 and female 11, the age was 19- 60-years-old with an average of 36 years) with thoracolumbar fractures were treated with posterior monosegmental pedicle screw fixation in our department. According to the AO classification, 19 patients with type A1 fracture and 9 with type A2.

[Therapeutic strategies of grade-III open fractures of tibia and fibula].

Objective: To explore early treatment and technique of grade-III open fracture of tibia and fibula and to summarize the experience of the treatment with external fixation.

Methods: The retrospective analysis were carried out in 168 cases of grade-III open tibial and fibular fractures. One hundred and twenty cases were treated with external fixation,and others were treated with intramedullary nail or amputated.
